Depilator Housing with Integrated Bearings and Gear Train
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair removal devices are complex and costly due to their numerous removable parts, leading to high manufacturing expenses and time, while seeking a solution that reduces complexity and cost while maintaining performance and reliability.
Innovation Solution
An electric depilation device with a hollow body composed of two one-piece half-shells that assemble to form a hair removal chamber, integrating support bearings and a gear train, and featuring a non-removable epilation head to simplify assembly and reduce part count, with a partition to prevent hair dissemination and enhance reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a removable hair removal head is used, then the device allows for easy maintenance and part replacement, but the device complexity and number of parts increase
Solution Approach 1:
The device is divided into a housing and a hair removal head assembly that can be separated. The head assembly includes the depilation head, support bearings, and gear train, which can be removed as a unit for maintenance while simplifying the overall part count through functional integration.
2Ease of manufacture
If multiple separate components are used, then the device allows for flexible assembly and manufacturing, but the manufacturing cost and assembly time increase
Solution Approach 1:
The support bearings for the depilation head and the immobilizing ribs for the motor are integrated directly into the housing structure rather than being separate components. This merging of functions reduces the number of parts and assembly steps while maintaining manufacturing flexibility through modular head assembly.
3Adaptability or versatility
If the depilation head is removable, then the device allows for head replacement and versatility, but the reliability and assembly simplicity decrease
Solution Approach 1:
The depilation head is designed as a removable assembly that can be replaced, providing versatility. The segmentation allows the head to be separated from the housing for replacement while the integrated support bearings and immobilizing ribs ensure reliable reassembly with proper positioning.

AI summary
The apparatus has a hollow body comprising an electric motor (15) associated with a worm train rotatingly driving a rotary mechanical depilation head (10). The body comprises two half-shells (2), which combinedly define a depilation chamber opened at the level of a depilation window defined by an edge of each half-shell. The head is placed at inside the window to be flush at the level of the window. One of the half-shells integrates support bearings (11, 12, 29-32) supporting the head and/or the worm train and/or ribs (16) for immobilizing the motor.
